Within the world of cartesian-style 3D printing, there are two distinctstylesof 3D Printers. The first of these is known as a direct drive printer,whichhas the extruder assembly connected to the hotend assembly to pullthefilament directly from the spool. The second style of printer is theBowden-style setup, in which the extruder is located separately and feedsthefilament from the extruder to the Hotend Assembly via a PTFE guide line. This is why we stock this 1.75mm Bowden Teflon PTFE Tubing, with an IDxODof2x4mm and a total length of 1 metre. This tubing is fitted betweentheExtruder Assembly and hotend assembly in Bowden-style printers, which actsasa simple low-friction guide for the filament to be pushed down, andensuresthat the drive from the extruder effectively gets the 3D Filament towhere itneeds to be. It is easy to install by simply pushing the end into theJohnGuest fitting of a Bowden connector, which ensures that it fits firmlyandsnugly within the tight grip, but is still easy to remove if necessarywhenthe time comes to replace the tubing. _ Note: These PTFE Tubes are compatible with the V6 PC4-01, PC4 M6 andPC4M5 Bowden Connectors, and should fit snugly and firmly within the tightgripof these fittings._ 1.75mm Bowden Teflon PTFE Tube - Technical Specifications:| – PTFE (Polytetrafluoroethylene) - Filament Diameter Compatibility

It fits betweentheextruder assembly and the hotend assembly and provides a clean, secureandlow-friction guide line for filament to travel within as it gets pushed bythedrive gear. This keeps the filament completely in control and safe fromdustor external damage, which is important for ensuring that all of thedifferentparts on the printer work together without any hassles. |
